I watched a show on a local cable channel last night about the history of skiing. Particularly Nordic and ski jumping disciplines. It covered stuff from the 1800’s to the 1994 Olympics in Norway. It was really cool to see the development of the skiing style and the change in skis over time. Some of ...

Does it look like they've done more than prebend the core and wet out the wood preping it for layup? It difficult to tell, but do you think its more than that? I can't watch the video here, but I did look at it this past weekend, and it seems like they use more thinner layers than we have been. Mayb...

Actually the 9.4 mm (9.7mm actually I have my SS here) is the deflection in the bottom graph. If you hover over the graph line it will show you a coordinate at that point. The only data that I have modified is the ski dimension data, running length, nose width, etc (stuff in the yellow boxes). The f...

Nice graphics!! Thats a great idea. Where's the risque parts? Is there a zoom fuction? LOL Sorry... its the beer talking. The blades I mention in the other thread didn't work for you? I just cut out a ski the other day and they did just fine and seems like it will do most of another ski. I only had ...

Have a look at this. I have entered most of the skis from this web site and the two I have made and skied. My skis have ~9.4 and 5 mm of deflection. The soft skis are fun and easy to ski the stiff ones are a real challenge to ski. This works well for a comparative analysis and can give you some idea...

This is the third time our mountain has smiled at us this year. Its a bit weak this time and probably won't last



Squint to see Ben Lomond smile at you.

It sure is starting slow here this year.

I think the sweet spot is a function of the stiffness of and flex pattern of the ski. My skis with the small sweet spot are very stiff and have a long mount area. I don’t have the SS here to look it up, but I think the mount area was 450 mm long. Most of the skis I have looked at have short 300 mm a...

If you have a table saw you can stack laminate the boards instead of cutting the strips out first. Get wood that is planned on the two wide surfaces. Stack them as deep as you can cut with the saw and rip your ski core part from that and glue the two book matched part together to get the full width ...

I just noticed also that the blades above are an up cut blade. If you do the trim cut from the bottom of the ski you shouldn't have any issue with top sheet chipping. The blade will be cutting as it is pulled up through the ski pulling the top sheet into the core. I didn't thave any issue with these...

Those are some aggressive looking blades, what are you using for a topsheet? I was worried about tearing mine. krp8128, I have glass top sheets sometimes with a bit of silk for color. These blades are just for removing the flash. I vacuum bag so everything gets pulled down to the edges. I'm not sur...

OHya, I use a 36-40 grit sanding disk. Removes the resin/glass and sparkes on the edge. It tells you when to stop.

AUtahSkiBuilder, you should put this where people will see it. Try the "Ski Design and Layup" section.

You can just run the blade along the edge. The hardened steel of the edge is difficult to cut with a scroll saw. Here is a pack of the blades that I found to work best. I can get around most of a pair of skis with one blade. When clean up the edges with the right angle grinder so the router guide be...

I do the recess before the core is profiled. I did it the other way around the first time and ran into too many problems trying to hold down the profiled core. http://home.comcast.net/~mhafte/images/recess1.jpg Here is a picture of the table I made to cut the recess. The router bit is a ½” 4 flute s...

I had the same issue with my first pair of skis. I was luck because I noticed the problem before I did the lay-up. I found that if I used the templates to hold the base in position while the edges were being glued to the base I could straighten out the base. Once the edges were glued to the base eve...
